With reference to FIG. 1 to FIG. 4, the implementation example provides a type of portable straw, including the limiting component, the adjusting component and the straw body 25. The said limiting component includes first limiting disc 19 and second limiting disc 20 which are mutually symmetrical and kept at a given gap, and first limiting disc 19 and second limiting disc 20 are connected through a cylinder.

With reference to FIG. 4, the said adjusting component includes first adjusting disc 11 and second adjusting disc 12 which are mutually symmetrical and able to relatively rotate, the said cylinder passes the center of first adjusting disc 11 and the second adjusting disc 12, and first connecting tube 13 and the second connecting tube 14 separately extends from one side of first adjusting disc 11 and second adjusting disc 12. First connecting tube 13 and second connecting tube 14 are separately sited by 2 sides of the cylinder so as to ensure parallel axis of first connecting tube 13 and second connecting tube 13 of the straw at the folded state, effectively reduce space volume and facilitate the carrying. The tops of first connecting tube 13 and connecting tube 14 are connected through foldable hose 15, and the bottom ends of first connecting tube 13 and second connecting tube 14 are separately inserted into straw body 25. With reference to FIG. 3, the cylinder passes the center of first adjusting disc 11 and second adjusting disc 12, and is limited by first limiting disc 19 and second limiting disc 20 (first limiting disc 19 and second limiting disc 20 is separately set at the outer sides of first adjusting disc 11 and second adjusting disc 12 so as to adjust the distance between first adjusting disc 11 and second adjusting disc 12) to ensure stable structure of the product. In this product, one end of first connecting tube 13 and second connecting tube 14 is respectively connected through foldable hose 15, and the other end is inserted into detachable straw body 25. When first adjusting disc 11 and second adjusting disc 12 relatively rotate, the straw may be extended or folded for easy carrying.

In addition, since straw body 25 and foldable hose 15 are connected with first connecting tube 11 and second connecting tube 12 at a detachable mode, straw body 25 is made of metallic material, and foldable hose 15 is made of silicone, the product is easy in carrying, eliminates the damage resulted from the compression or bending-folding during the carrying process and may be washed after use, which facilitates the repeated uses and saves the cost. Especially, due to the materials used in straw body 25 and foldable hose 15, after washing, they may be subjected to high-temperature sterilization, which protects the human body from injury by the straw-carrying bacteria or hazardous substances. Particularly, when the user intakes hot drinking or acidic drinking through this product, it protects the user's health from impairment by the harmful substances released from foldable hose 15.

Further, with reference to FIG. 4 to FIG. 5, the side of first adjusting disc 11 close to second adjusting disc 12 is provided with an annular groove, spring 17 is fixed inside the said annular groove, the opening of the said annular groove is provided with annular fixing disc 16 to fix the groove, fixing disc 16 is provided with several clamping pillars 18 which pass fixing disc 16 and are evenly arranged, clamping pillar 18 can axially move and the end of clamping pillar 18 which is sited in the groove is connected with spring 17, the end of second adjusting disc 12 close to first adjusting disc 11 is provided with several clamping grooves, and the end of clamping pillar 18 close to second adjusting disc 12 is spherically matched with the said clamping groove. When first adjusting disc 11 and second adjusting disc 12 relatively rotate, since the clamping pillar and the clamping groove are slightly spherically matched, clamping pillar 18 is able to move out from the previous clamping groove. When clamping pillars 18 gradually move out from the clamping groove, clamping pillar 18 may axially move towards first adjusting disc 11, clamping pillar 18 exerts a pressure onto spring 17 and in turn axially contracts to the groove of first adjusting disc 11. When clamping pillar 18 enters the next clamping groove, due to the action of the spring, clamping pillar 18 will fast extends and enter and clutch the next clamping groove, which stabilizes the structure of the adjusted straw, somewhat fix the rotation angle of the straw to make clamping pillar 18 well clutch the clamping groove during the rotation process, and effectively improves the product-user's hand feeling and qualitative feeling.

Further, the said cylinder includes the key 22 extending from the center of first limiting disc 19 towards second limiting disc 20, and also includes plug 21, the end of plug 21 close to first limiting disc 19 can pass the center of second limiting disc 20 and insert into key 22, and the other end of the plug 21 is clamped with second limiting disc 20 (the end of plug 21 apart from first limiting disc 19 is not allowed to pass the center of second limiting disc 20), which facilitates detaching and fixing of first limiting disc 19 and second limiting disc 20. First limiting disc 19, second limiting disc 20 and cylinder are on a same axis, which is advantageous to improve the structural stability of the product.

Further, the outer wall of the connection end of foldable hose 15 is provided with several annular projections 26, and foldable hose 15 can insert into first connecting tube 13 and second connecting tube 14, which effectively improves the sealing capacity of the connections between foldable hose 15 and first connecting tube 13/second connecting tube 14.

Further, the outer walls of the bottom of first connecting tube 13 and second connecting tube 14 are provided with several annular grooves (not shown in drawings), and the inside of the said annular groove is provided with water-sealing rings. When straw body 25 inserts into first connecting tube 13 and second connecting tube 14, the water-sealing ring made of silicone will effectively improve the sealing capacity of the connections between straw body 25 and first connecting tube 13/second connecting tube 14.

Further, slides 23 are provided between first limiting disc 19 and first adjusting disc 11 and between second adjusting disc 12 and second limiting disc 20, and they prevent the product from reduction of service life resulted from the relative friction between first limiting disc 19 and first adjusting disc 11 and between second adjusting disc 12 and second limiting disc 20, and make first adjusting disc 11 and second adjusting disc 12 rotate smoothly.

Further, the outer sides of first limiting disc 19 and second limiting disc 20 are provided with cover plate 24.

As per the above description, each part of the product is connected at the detachable mode, which facilitates the replacement of the damaged parts, washing and repeated use. In the product, the cylinder is used to in-series connect slide 23, first adjusting disc 11, spring 17, limiting disc and the second adjusting disc 12, and they are in a same axis so as to ensure the rotation of first adjusting disc 11 and second adjusting disc 12 on a same axis. First connecting tube 13 and second connecting tube 14 are connected with foldable hose 15, which may realize extension and folding of the straw when first adjusting disc 11 and second adjusting disc 12 relatively rotate with the cylinder as the shaft. The limiting component between first adjusting disc 11 and second adjusting disc 12 stabilizes the structure of the product after adjustment (after the extension angle of the product is adjusted, under the co-action of clamping pillar 18 and clamping groove, its structure keeps stable). Meanwhile, straw body 25, foldable hose 15 and adjusting component are connected at the detachable mode, which facilitates the carrying and washing. Since straw body 25 is connected with first connecting tube 13 and second connecting tube 14 at the detachable mode, the user may replace corresponding-sized straw body 25 depending on the size of his cup, which expands the use range and enhances users' satisfaction.

During the use, since the adjusting component is provided with first adjusting disc 11 and second adjusting disc 12 which are mutually symmetrical and able to relatively rotate, the straw may be freely adjusted within 150-degree rotation range. The coordination of clamping pillar 18 and clamping groove makes the structure of the product stable after its adjustment. When the straw is at the folded state, it may be clamped at one side of the cup so as to avoid shaking or dropping. Through adjusting the folding angle, the straw will suit for more use conditions. For example, for a man holding the cup at standing state, the angle may be adjusted depending on his pose. When the cup is on the table, angle within 150-degree may suit for most persons' sucking pose, and the patient lying on the bed may suck drinking or fluid foods through the product.

In addition, the action of spring 17 makes clamping pillar 18 fast slide in or slide out during relative rotation of first adjusting disc 11 and second adjusting disc 12, renders close coordination between clamping pillar 18 and the clamping groove, and effectively improves the product-user's hand feeling and qualitative feeling.
